DQOR'HANG'ER.

Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed April 10, 1919. Serial No. 289,054.

To all whom it may concern:

Be it known that I, Lnvr L. PARSONS, a citizen of the United States, residing at New York city, New York, have invented certain new and useful Improvements in Door-Hangers, of which the following 1s a clear, full, and exact description.

This invention relates to door hangers and particularly to door hangers of the, type disclosed in my application Serial No. 132,726, filed November 22, 1916, and a general object of the invention is to improve and simplify the construction disclosed in said application while retaining all of its advantageous features, to the end that not only is a very rigid structure produced and one which is less costly to manufacture and to assemble but also one in which any distortions of the tracks, due to more or less careless installation, will not affect the an important feature of the invention relates to the novel construction of the track supporting frames or members, whereby the supporting rollers for the door hanger and the guiding rollers therefor are brought close together.

Other objects and important features of the invention will become apparent from the following description and claims when taken in connection with the accompanying drawings which illustrate the preferred embodiment of the invention, and in which Figure 1 is a front elevation of a portion of the improved hanger, with parts broken away to better show the construction;

Fig. 2 is a sectional view taken at about the line 22 of Fig. 1;

Fig. 3 is a detail of the bracket which supports one of the guide rollers;

Fig. 4 is a perspective view of the track, which is connected to the door hanger frame;

Fig. 5 is a front elevation of the hanger showing the supporting brackets by which it is attached to a door frame or other structure;

Fig. 6 is a bottom view of the hanger;

Fig. 7 is a perspective view of the main supporting frame member;

Fig. 8 is a sectional view on the line 88 of Fig. 5; and

Fig. 9 is a similar section but showing a slight modification of the structure from thatshown in Fig. 8.

Referring to the drawing, the illustrated door hanger comprises a main supporting frame member 2 of novel construction, on which is carried and guided a roller carriage which in turn supports the door hanger frames in a manner to be hereinafter described. This frame member 2 is preferably formed of sheet metal of suitable thickness and comprises a top plate 4 bent over to form a eownwardly projecting front portion 6 and also a downwardly projecting rear portion 8. This rear portion 8 is bent forwardly at 10, Figs. 7, 8 and 9, upwardly at 12, forwardly again at 14 and downwardly at 16, the portions 12, 14 and 16 forming on their outer faces a track for the rollers 18 of the carriage, while the under faces of said portions form a guiding track for rollers 20 carried by the hanger frame connected directly to the door. The frame member 2 is supported from the framingof the door or other structure to which the hanger is to be attached by brackets 22, Fig. 5, said brackets being attached by means of bolts or other suitable securing 'ElLQSHS.

The track formed by the portions 12, 14 an 16 preferably in the form of an inverted U, the portion 14 forming the top of the inverted U being flat on its outer portion, the corners being slightly rounded as clearly shown in Figs. 7 and 9, and the roll- 18 are preferably shaped to conform to this track, said rollers having flanges which closely fit the sides thereof, which flanges are slightly beveled to reduce the friction along the sides of the track, and also to provide for a limited rocking movement of the rollers upon the track.

The rollers 18 are mounted in a roller carriage clearly shown in Fig. 2 and this carriage may be constructed as shown and described in my application above referred. to, but for the purposes of showing a practical embodiment of my invention in the present application, I have shown said carriage as consisting of plates 24 and 26, the roller axles passing through said side plates and being suitably secured therein. As shown in Fig. 2, the width of each of the rollers, or its dimension along its axis, may be somewhat less than the space between the side frames of the carriage, thus providing for limited lateral movement of the rollers. In order to reduce or practically eliminate the noise as the door is opened and closed.

incident to this lateral movement, the space between the side frames of the carriage and the ends of the rollers may be made somewhat greater than the desired movement, and metal washers 28 may be placed between the, ends of the rollers and the respective sides of the carriage. In some cases, how'- ever, it may not be necessary to use these washers and they may be omitted, as shown, for instance, in Fig. 9.

For supporting the door on the carriage, a hanger frame is provided and this consists preferably of a piece of metal 30 bent in to form a U, as will be understood from a consideration of Figs. 1, 5, 6, 8 and 9. Two of these U members are provided as shown at Figs. 4 and 5, and they are connected to the door in any suitable manner. Fastened to these hanger frames is a plate 32, Fig. 1, whose upper portion is bent as shown in Figs. 4, 8 and 9, to form a U-shaped rollerengaging track 33, said track conforming to the shape of the rollers 18 on which it rijplles 1e hanger frames 30 Carry each a bracket 3% in the form of a channel member 3%, Figs. 3, 8 and 9, said brackets being pivotally secured to the sides of the frames 30 by any suitable means, as for instance, by screws 35 as shown in Fig. 1. Carried in said brackets 34 are the guiding rollers 20 already referred to, these rollers acting to reduce the vertical play of the hanger and to prevent excessive endwise rocking of the door, one roller 20 being provided near each end of the hanger. Adjusting screws 36 enable the brackets 3% to be adjusted to bring the rollers 20 into comparatively close contact with the undersurfaces of the track 14 carried by the frame member 2, said rollers being formed with a central flange which fits in between the sides of the inverted U-shaped portion of said frame member. Preferably the screws 36 are turned so as to bring the roller 20 quite close to or practically in contact with the under-surface of the track 14, as indicated in Figs. 8 and 9.

By the construction shown, the rollers 20 are brought very close to the rollers 18, being separated therefrom approximately only a distance equal to the thickness of the metal forming the track it. As result, any deformation of the track or misalinement thereof, due to settling of the building or to more or less careless installation, will not result in any undue friction in the action of the doors. It will also be noted that by reason of the fact that both the supporting frame 2 for the rollers and the track 33 for the hanger frame are formed each of a single piece of metal, these parts can be readily rolled to the desired shape, thus cheapening the cost of manufacture. It is of course understood that the plate 32 and the hanger frame3O may also be formed of a single piece of metal instead of in two pieces, as shown.

The side frame 26 of the roller carriage has portions 37 bent over into the path of movement of the plate 32 to be engaged thereby as the door is opened or closed to move the carriage along the track, as will be readily understood. The ends of the hanger are provided with bent over plates 38, Fig. 5, and on the inside of these plates are provided bumpers to deaden the sound of contact of the carriage when the door reaches either end of its movement.

The overhang 6 of the frame member 2 extends below th upper bend of the plate 32 and gives a finished appearance to the structure.

While I have shown and described a pre ferred en'ibodiment of the invention, it is of course to be understood that I do not limit myself to the exact construction disclosed, as variations may be resorted to within the scope of the invention and some of the improvements may be used without others.

What I claim as new is:

1. A door hanger comprising, in combination, a supporting frame of sheet metal having a track formed integral therewith by bending the metal in the form of an inverted U, rollers engaging the upper surface of said track, a hanger frame having a track member to ride upon said rollers, and guiding rollers carried by said hanger frame fitted into and guided by the under portions of said ii-shaped track.

2. A door hanger comprising in combination, a sheet metal frame member having a top plate and a back plate, said top plate having a forwardly bent overhang, said back plate having a forwardly extending portion bent in the form of an inverted U to afford a roller bearing surface, a roller carriage carrying rollers engaging said surface, and a hanger frame separate from said roller carriage and having a sheet metal plate extending upwardly and under said overhang and being bent to form a U for engagement with the rollers in said carriage whereby said hanger frame is supported.

3. A door hanger, comprising in combination a supporting frame having a track carried thereby, said track formed of sheet metal bent in the form of an inverted U, and having upper and lower roller engaging surfaces, rollers fitting the upper surface of said track, a hanger frame having a track member in the form of a U, fitting and riding upon said rollers, and guiding rollers carried by said hanger frame, and fitted into and guided by the under portions of said inverted U-shaped track.
